Antique Mining Equipment

Apr 27, 2017 The early mining of iron ore in Minnesota was carried on with the most primitive kind of tools. The pioneers used only such equipment as could be packed from Duluth through one hundred miles of forest to the first mines on the Vermilion Range and the operations were carried on with picks, shovels, hand drills and wheelbarrows, the ore being hoisted in buckets with a horse winch and carted

History of Mining Equipment & Practices

Apr 11, 2017 Based upon a recent investigation of truck vs. rail haulage in bituminous-coal mines, Toenges and Jones conclude that with equipment in its present stage of development and within the range of conditions studied, for a new mine a dual haulage system would effect a saving in transportation cost if the round-trip haul exceeds 2.7 miles.
